本文基于在实验过程中遇到的误标数据,考察EBSD测量过程中发生误标的原因。涉及的材料包括密排六方结构(镁合金)、体心立方结构(电工钢)金属。统计结果表明,密排六方结构中的误标点(块)主要以30°〈0001〉和30°〈■〉的取向关系出现;体心立方结构中的误标点(块)多是30°〈111〉的取向关系,而且误标点具有重合位置点阵(CSL)关系。误标具有明显的晶粒取向选择性。最后提出一些的减少误标的办法。
In this paper, based on the error data encountered in the experiment process, investigate the cause of the error occurred in the EBSD measurement process. Materials involved include hexagonal close-packed structure (magnesium alloy), body-centered cubic (electrical steel) metal. The statistical results show that the mismatch points (blocks) in the hexagonal close-packed structure mainly appear in the orientation of 30 ° <0001> and 30 ° <■>. The number of false marks (blocks) in the body-centered cubic structure is mostly 30 ° <111 >, And the mis-punctuation point has a coincident location lattice (CSL) relationship. Mislabeling has obvious grain orientation selectivity. Finally, some ways to reduce the false standard.
